United States Patent GLIDE FASTENER Eduard Stark, Biel-Mett, Switzerland, assignor of seventyfive per cent to Alfred Schmidhalter, Ried-Brig, Switzerland Application January 15, 1952, Serial No. 266,478 Claims priority, application Switzerland February 2, 1951 8 Claims. (Cl. 24-207) This invention relates to glide fasteners having a means enabling the glide members to be disengaged from one of the parts to be connected with each other, in order to completely separate these parts from each other.

The novel glide fastened is characterized in that the glide members are arranged to be moved onto a first coupling half fixed to one of the parts to be connected with each other, the second coupling half fixed to the other part being engageable with and disengageable from the first coupling half on the glide members riding on the latter.

A glide fastener serves to hold together two parts such as cloth bands or the like having a bead each. The glide members of glide fasteners are not clamped fast to the parts as the clamps of the commonly known slide fastenera, but each glide member is shaped to slidably engage both beads. Thus, the glide members can, contrary to the above mentioned clamps, slide along the beads. The glide members are connected with one another by flexible means such as strings or the like, for instance.

The accompanying drawing illustrates by way of example one embodiment of the invention.

Fig. l is a top view of the glide fastener in uncoupled condition,

Fig. 2 is a sectional view taken along the line 2-2 of Fig. 1.

Fig. 3 is a View corresponding to Fig. 1 but with the glide fastener in coupled condition.

Fig. 4 is a sectional view taken along the line 44 of Fig. 3.

Fig. 5 is a bottom view of the glide fastener in engaged position and at a slightly reduced scale.

The two parts to be connected with each other are formed by the cloth strips 1 and 2, for instance. Each of these strips has a head 3 or 4 respectively. The beads being in the position of Fig. 4 with regard to each other, the lock 7 and the glide members 6 coupled with one another by means of strings 5 clamped fast below portions 7 of the members 6 may glide along the heads 3 and 4 which they engage in a well-known manner.

On one end portion of the bead 3 a split guide tube 8 is clamped fast, onto which the glide members 6 may be pushed to ride thereon. Therefore, the outer surface of the tube 8 forms a slide surface for the members 6. As shown in Fig. 1, the guide tube 8 is longer than the lock 7 together with the row of all the members 6 butting against one another. On the corresponding end of the head 4 a clamping sleeve 9 is clamped fast. It serves the purpose of engaging in a left-hand rounded portion 10 of the tube 8 (Fig. 4) when the disengaging coupling of the glide fastener consisting of the parts 8 and 9 is in engaged condition. The rounded portion 10, whose inner surface serves the clamping sleeve 9 as a guide, imparts a radial pressure onto the clamping sleeve 9 thereby preventing the latter from accidentally leaving the coupled position. Therefore, the split tube 8 is preferably made from sheet metal.

When the two parts 1 and 2 are to be completely separated from each other, the glide members 6 are drawn by means of the lock 7 towards the lower end of the heads 3 and 4 in Fig. 5. The members 6 leave the beads 3 and 4 one after another in order to ride on the split guide tube 8. This condition is shown in Fig. 5. As the head 4 is now no longer coupled with the glide members 6, the clamping sleeve 9 can be drawn off the guide tube 8 towards the top. Fig. 1 illustrates the parts 1 and 2 as being completely separated from each other. On coupling the parts 1 and 2 again with each other the clamping sleeve 9 is inserted from the top in Fig. 1 with its pin 11 in front into the rounded portion 10 of the tube 8, whereupon the two coupling halves 8 and 9 are again in the mutual position shown in Fig. 4. When the lock 7 is pulled towards the top in Fig. 5 the glide members 6 are drawn off the guide 8 one after another and afterwards run again on the beads 3 and 4 as illustrated in Fig. 5.

The guide tube 8 being longer than the lock 7 and all the members 6 butting against one another allows the pin 11 to be inserted into the guide tube 8 without any difliculty.

Instead of clamping the guide tube fast to a head, it may also be fixed to the flat portion of the part 1 or to any other portion. The coupling halves 8 and 9 may be shaped in any manner other than as shown in the drawing.
